Miniaturized Matrix Solid-Phase Dispersion for the Analysis of Ultraviolet Filters and Other Cosmetic Ingredients in Personal Care Products

open access: yesSeparations, 2019
A method based on micro-matrix solid-phase dispersion (μ-MSPD) followed by gas-chromatography tandem mass spectrometry (GC−MS/MS) was developed to analyze UV filters in personal care products.

Analytical Solutions to Minimum-Norm Problems

open access: yesMathematics, 2022
For G∈Rm×n and g∈Rm, the minimization min∥Gψ−g∥2, with ψ∈Rn, is known as the Tykhonov regularization. We transport the Tykhonov regularization to an infinite-dimensional setting, that is min∥T(h)−k∥, where T:H→K is a continuous linear operator between ...

Analytic solution of Bremsstrahlung TBA [PDF]

open access: yesJournal of High Energy Physics, 2012
We consider the quark--anti-quark potential on the three sphere or the generalized cusp anomalous dimension in planar N=4 SYM. We concentrate on the vacuum potential in the near BPS limit with $L$ units of R-charge. Equivalently, we study the anomalous dimension of a super-Wilson loop with L local fields inserted at a cusp. The system is described by a

Application of modified exp-function method for strain wave equation for finding analytical solutions

open access: yesAin Shams Engineering Journal, 2023
The strain wave equation in micro-structured solids, which is significant in solid physics, is offered for consideration in this work. This is accomplished using the modified exp-function method, which is one of the most powerful ways for constructing ...

Analytical solution to approximate equations of the launch vehicle motion under the gust action for the dynamic loading calculation

open access: yesAdvanced Engineering Research, 2022
Introduction. The launch vehicle (LV) in flight and the dynamic components of loads from the impact of a trapezoidal wind gust are considered. It is proposed to determine the dynamic components of the force factors using analytical solutions for the ...
